Alcatraz Island has not held inmates since 1963, but construction next to the famous prison is under way.
A 72-year-old water tower, the most visible feature on Alcatraz Island from San Francisco, is wrapped in white tarp and scaffolding as it undergoes more than $1 million in repairs.

San Francisco officials introduced preliminary plans for a 10-year, multimillion-dollar project that could result in the construction of new police and fire facilities, a new jail, and potentially a new San Francisco Superior Courthouse.
